Recent research shows alarming rates of food insecurity among them. This review explores research focussing on food security of TFWs in Canada and the United States, summarizes findings, and identifies research gaps. Online databases, including MEDLINE, Web of Science, Scopus, Google Scholar, and government and nongovernment websites, and websites of migrant worker-supporting organizations were searched for peer-reviewed and non-peer-reviewed papers and reports published between 1966 and 2020 regarding food security of TFWs. Articles reviewed were analyzed to determine publication type, country, year, target population, and main findings. Content analysis was performed to identify major themes. Of 291 sources identified, 11 met the inclusion criteria. Most articles (n = 10) were based on studies conducted in the United States. The prevalence of food insecurity among TFWs ranged between 28% and 87%. From the content analysis, we formulated 9 themes, representing a diversity of perspectives, including access to resources, income, housing and related facilities, food access, dietary pattern and healthy food choices, and migrant's legal status. Instruments reported for the measurement of food security include USDA Household Food Security Survey Module (HFSSM; n = 8, 72.7%), the modified version of the USDA HFSSM (n = 1, 9%), hunger measure (n = 1, 9%), the modified CDC's NHANES (n = 1, 9%), and 24-h recall, diet history, and/or food-frequency questionnaire (n = 3, 27.3%). Factors impacting food security of TFWs working under the Seasonal Agricultural Worker Programs (SAWPs) in North America are understudied. There is a need to advance research looking particularly at policies and regulatory and administrative aspects of the SAWPs to improve the food security of this cohort. There is also a need for qualitative studies that explore lived experiences and perspectives of TFWs and key informants. Longitudinal studies may be useful to examine various factors, including policy-related, contributing to food insecurity of TFWs over time.</p>","PeriodicalId":72101,"journal":{"name":"Advances in nutrition (Bethesda, Md.)","volume":"13 5","pages":"1603-1627"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9526858/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143069074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PubMed, Scopus, Web of Science, and Google Scholar were searched up to March 2021. Prospective, observational cohort studies, nested case-control, and case-control designs that investigated the association between antioxidants and PD risk were included. A random-effects model was used to pool the RRs. The certainty of the evidence was rated using the GRADE (Grading of Recommendations Assessment, Development, and Evaluations) scoring system. In addition, a dose-response relation was examined between antioxidant intake and PD risk. Six prospective cohort studies and 2 nested case-control (total n = 448,737 with 4654 cases), as well as 6 case-control (1948 controls, 1273 cases) studies were eligible. The pooled RR was significantly lower for the highest compared with the lowest intake categories of vitamin E (n = 7; 0.84; 95% CI: 0.71, 0.99) and anthocyanins (n = 2; 0.76; 95% CI: 0.61, 0.96) in cohort studies. Conversely, a significantly higher risk of PD was observed for higher lutein intake (n = 3; 1.86; 95% CI: 1.20, 2.88) among case-control studies. Dose-response meta-analyses indicated a significant association between a 50-mg/d increase in vitamin C (n = 6; RR: 0.94; 95% CI: 0.88, 0.99), a 5-mg/d increment in vitamin E (n = 7; RR: 0.84; 95% CI: 0.70, 0.99), a 2-mg/d increment in β-carotene (n = 6; RR: 0.94, 95% CI: 0.89, 0.99), and a 1-mg/d increment in zinc (n = 1; OR: 0.65; 95% CI: 0.49, 0.86) and a reduced risk of PD. Overall, higher intake of antioxidant-rich foods may be associated with a lower risk of PD. Future well-designed prospective studies are needed to validate the present findings.

This recognition has been fruitfully employed in a number of issues in health and nutrition sciences; however, it has not been incorporated into education. Nutrition and dietetics students generally learn very little or nothing on the subject of evolution, despite the fact that evolution is the process by which our genetically determined physiological traits and needs were shaped. In the present Perspective article, 3 examples of topics (inflammatory diseases, nutrition transition, and food intolerance) that can benefit from evolutionary information and reasoning are given, with relevant lines of research and inquiry provided throughout. It is argued that the application of evolutionary science to these and other areas of nutrition education can facilitate a deeper and more coherent teaching and learning experience. By recognizing and reframing nutrition as an aspect and discipline of biology, grounded in the fundamental principle of adaptation, revelatory light is shed on physiological states and responses, contentious and unresolved issues, genomic, epigenomic, and microbiomic features, and optimal nutrient status and intakes.</p>","PeriodicalId":72101,"journal":{"name":"Advances in nutrition (Bethesda, Md.)","volume":"13 5","pages":"1431-1439"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9526857/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142302205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review aimed to comprehensively describe, and explore characteristics of, national strategies to reduce sodium concentrations in packaged foods, and assess progress toward achieving national goals. A secondary aim was to understand the number, type, and variation of food category sodium targets set by countries compared with WHO global sodium benchmarks. National sodium reduction reformulation strategies were identified from a search of peer-reviewed and gray literature up to December 2019 supplemented by verified information from key contacts and experts up to December 2020. Key characteristics of countries' strategies were extracted, synthesized, and descriptively analyzed, including details of reformulation strategies and evaluation data. Country targets were mapped to the WHO global sodium benchmarks, and the number and variation of country sodium targets by WHO food categories were determined. Sixty-two countries had reformulation strategies to reduce sodium in packaged foods, and 19 countries had evaluated their reformulation strategies. Forty-three countries had sodium targets, which varied in type of targets (maximum sodium concentration: n = 26; maximum concentration plus relative reduction/average/sales-weighted average: n = 8; relative reduction: n = 7; average: n = 2), number of food category targets (range: n = 1 to 150), and regulatory approach (voluntary: n = 28; mandatory: n = 9; both: n = 6). Eight of 34 countries mapped to the WHO benchmarks had targets for just 1 specified food category (bread products). One-third of all countries were implementing national strategies to reduce sodium concentrations in packaged foods including establishing targets and/or processes for industry engagement. This review determined that there is scope to improve most countries' strategies. There has been limited progress in implementing and evaluating strategies between 2014 and 2019, and regional and income-level disparities persist. The WHO global sodium benchmarks present an important opportunity to accelerate reformulation action globally.</p>","PeriodicalId":72101,"journal":{"name":"Advances in nutrition (Bethesda, Md.)","volume":"13 5","pages":"1820-1833"},"PeriodicalIF":0.0,"publicationDate":"2022-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9526819/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144181335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
